Introduction
Living and working in both Australia and the UK, Barrie Patrick Marmion was a meticulous clinical microbiologist and academic; devoted to education, research and development within pathology, immunology and virology. His contribution to microbiology was invaluable in regards to the development of an effective Q fever vaccine.
This report will examine Marmion’s research with respect to developing and promoting a Q fever vaccine, critically evaluating the impact of this accomplishment on disciplinary knowledge within microbiology and the broader medical community. A self-assessment concerning the research process, implementation of peer feedback and implications for further learning will also be included.

Primarily, these challenges involve determining the factors that affect host susceptibility to this disease to facilitate early detection and treatment where necessary. This is particularly significant as only 40% of Q fever cases are symptomatic, and hence, this infection often exists undiagnosed within humans and may be spread unknowingly (Gidding, H. et al. 2009). Furthermore, despite the effectiveness of Q fever vaccines, this does not correspond with widespread use among people working in high risk areas – namely veterinary fields. This is reflected in a study undertaken by Sellens, E. et al. (2016) who discerned that within Australia, only 74% of veterinarians and 29% of veterinary nurses had obtained Q fever vaccination (2016); statistics that should be considerably higher given the effectiveness of the vaccine and potential exposure to infection associated with these careers. Therefore, whilst Marmion’s work is of high significance in regards to vaccine effectiveness, it’s impact is restricted by the relatively limited use of such vaccines in high risk …show more content…
Moreover, Marmion’s contribution has inspired continued research and advancement into the efficacy of Q fever vaccination, creating avenues through which scientific and medical knowledge in this area may be further pursued. Despite his work being highly regarded, the impact of Marmion’s achievements on a whole-discipline level has been restricted, as seen through his low citation count. Whilst this can partially be attributed to the highly specialised nature of his research, it also becomes apparent that Marmion’s findings lose some degree of influence when considered separately to the subsequent discoveries made by his colleagues in this area that otherwise lend weight to the significance of his
The authors used a historical timeline to introduce a need. Stressing the number of lives lost allows the authors show the importance of vaccines. The repeated emphasis on those lives being the lives of children played on the emotions of readers. Once the need is established Lee and Carson-Dewitt clarify the use of “a dead or mild form of a virus” to create a vaccine (Lee, Carson-Dewitt, 2016, p.2). The distinction of the types of
The first discovery was made in 1952, in the developing field of virology. Virology is the study of viruses and how they behave. To develop the vaccines for the viruses, researchers infected the HeLa cells with many types of infections, such as measles, mumps, and the infamous poliomyelitis virus, also known as Polio. According to the Centers for Disease Control and Prevention (CDC), whose mission is to save lives and protect people’s health security, Polio is a "crippling and potentially deadly infectious disease caused by a virus that spreads from person to person invading the brain and spinal cord and causing paralysis" (Freeman). Jonas Salk, who was a virologist at the National Foundation for Infantile Paralysis (NFIP), used inactivated viruses (virus particles grown in culture and then killed by a form of heat) to create a polio vaccine. Salk drew blood from about two million children, which the NFIP checked for immunization.Through the collection of many HeLa cells and trial and error, the polio vaccine wa...

The effectiveness of vaccinations continues to be proven (Malone and Hinaman n.d.). For example, after development of the measles vaccine and the implementation of the vaccination program, the number of reported measles cases declined from 57,345 in 1977 to 2587 in 1984( CDC 2010 ). However, even though vaccinations have been proven safe and effective; there are still risks as well as the implication that not every person who is vaccinated will obtain immunity. That being said, serious damage from vaccination is a rare occurrence (Malone and Hinaman). A Glanz study (2013) from the Vaccin...
The article’s information is presented with the goal of informing a reader on vaccines. The evidence is statistical and unbiased, showing data on both side effects and disease prevention, providing rates of death and serious illness from both sides. This evidence is sourced from a variety of medical organizations and seems reliable, logical, and easily understood, no language that would inspire an emotional response is used. The validity of studies is not mentioned in the article, but it does encourage readers to investigate further to help make a decision. The article allows a reader to analyze the presented evidence and come to their own

In the article,” Childhood Immunization Controversies: What are Parents Asking?” Dr. Daniel R. Bronfin gives s thorough history and current evaluation of child immunizations. Dr. Bronfin breaks down several different childhood immunizations from Smallpox to measles. During his break down of each of the common diseases, he gives a history, how they developed a vaccine, and how the effects of the vaccine is currently working. Dr. Bronfin wrote this article to educate parents to the benefits of immunization.
Vaccines have been used to prevent diseases for centuries, and have saved countless lives of children and adults. The smallpox vaccine was invented as early as 1796, and since then the use of vaccines has continued to protect us from countless life threatening diseases such as polio, measles, and pertussis. The Center for Disease Control and Prevention (2010) assures that vaccines are extensively tested by scientist to make sure they are effective and safe, and must receive the approval of the Food and Drug Administration before being used. “Perhaps the greatest success story in public health is the reduction of infectious diseases due to the use of vaccines” (CDC, 2010). Routine immunization has eliminated smallpox from the globe and led to the near removal of wild polio virus. Vaccines have reduced some preventable infectious diseases to an all-time low, and now few people experience the devastating effects of measles, pertussis, and other illnesses.

Edward Jenner is often regarded as the “Father of Immunology” for his development of the smallpox vaccine. His remarkable discovery has laid the foundation for future scientists working with immunizations. Jenner’s impact is seen worldwide to this day with the complete eradication of the deadly smallpox virus. Edward Jenner’s Legacy will always live on as the first to vaccinate using a live virus. Vaccines are improving everyday, which benefits the public’s health, all thanks to Edward Jenner.
Vaccines have been around for hundreds of years starting in 1796 when Edward Jenner created the first smallpox vaccine. Jenner, an English country doctor noticed cowpox, which were blisters forming on the female cow utters. Jenner then took fluid from the cow blister and scratched it into an eight-year-old boy. A single blister came up were the boy had been scratched but it quickly recovered. After this experiment, Jenner injected the boy with smallpox matter. No disease arose, the vaccine was a success. Doctors all around Europe soon began to proceed in Jenner’s method. Seven different vaccines came from the single experimental smallpox vaccine. Now the questions were on the horizon. Should everyone be getting vaccinations? Where’s the safety limit? How can they be improved? These questions needed answers, and with a couple hundred years later with all the technology, we would have them(ncbi.nlm.nih.gov).
Vaccinations have significantly reduced the disease rate throughout the world. Usually, vaccines prove to be between 90 and 99 percent effective. This reduces disease and mortality rate by thousands every year (Jolley and Douglas 1). On average, vaccines save the lives of 33,000 innocent children every year (“Vaccines” 1). In addition, if a vaccinated child did contract the vaccine’s targeted illness, that child would, in general, have more mild symptoms than an unvaccinated child that contracts the same illness. These vaccinated children will have less serious complications if they do contract the disease; they will be much more treatable, and have a lower risk of death (Jolley and Douglas 2). The risks of not vaccinating greatly outweigh the small risks of vaccination. Diseases like measles and mumps can cause permanent disability. While there i...
Each day researchers are finding out about vaccines and are realizing that there are a lot more risks than benefits. Dr Phillip F. Incao explains: “Today, far more children suffer from allergies and other chronic immune system disorders than from life-threatening infectious disease. It is neither reasonable nor prudent to persist in presuming that the benefits of any vaccination outweigh its risk” (qtd in Spaker). While infectious diseases are becoming uncommon there is no need for any person to get vaccinated. There have been many issues surrounding vaccinations all around the world.
In Australia in the last ten years more then 137 known people have died and many more fallen very ill from contagious and infectious disease. Diseases such as diphtheria; tetanus, pertussis, poliomyelitis, measles, mumps rubella and Haemophilus influenzae, This is a great tragedy considering all these diseases are easily preventable by immunisation.
Today eighty percent of infants are being vaccinated for diphtheria; pertussis (whooping cough), polio, measles, tetanus and tuberculosis (Landrige 2000). This percentage is up from about five percent in the mid-1970s; however, the death toll from these infections is roughly three million annually. Millions still die from infectious diseases for which immunizations are non-existent, unreliable, or too costly. Vaccines all function with the same idea in mind, priming the immune system to swiftly destroy specific disease-causing agents, or pathogens, before the agents can multiply enough to cause symptoms (Landrige 2000). Classically, this priming has been achieved by presenting the immune system with whole viruses or bacteria that have been killed or made too weak to proliferate much (Landrige 2000).
